Normokalaemic periodic paralysis as the presenting manifestation of hyperthyroidism.

ABSTRACT

We report a 50 year old male admitted with complaints of episodic weakness. During the attack of paralysis there was no hypokalaemia. There were no clinical signs of thyrotoxicosis, but since thyroid function tests revealed hyperthyroidism, he was treated as a case of thyrotoxic periodic paralysis, with no recurrence of symptoms over 6 months.
